Sometimes I search my own site in Google to find content on various subjects like -
site:example.com car tires
Sometimes a SERPS featured snippet is shown (with both the text and image coming from my domain).
Is this an indication that this same featured snippet sometimes appears in the "wild"? (Like when someone searches for the general term "car tires" but not specifically from my domain.)
If so, that would suggest that when formatting pages so possibly Google does use them to create their featured snippets, you could test your efforts. Any experiences, thoughts or ideas on this?
